Draining the Fuel Tank

Drain the fuel tank when you will not be using the
machine for more than 30 days.
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and
others and can damage property.
• Drain gasoline from the fuel tank when the
engine is cold. Do this outdoors in an open
area. Wipe up any gasoline that spills.
• Never smoke when draining gasoline, and
stay away from an open flame or where a
spark may ignite the gasoline fumes.
1. Park the machine so that the left front side is slightly
lower than the right side to ensure that the fuel tank
drains completely.
2. Disengage the blades (PTO).
3. Set the parking brake.
4. Stop the engine and wait for all moving parts to stop.
5. Remove the ignition key.
6. Open the hood.
7. Squeeze the ends of the hose clamp together
and slide it up the fuel line toward the fuel tank
(Figure 28).

8. Pull the fuel line off the fuel filter (Figure 28) and
allow the gasoline to drain into an approved fuel
container or a drain pan.
Note: Now is the best time to install a new fuel
filter because the fuel tank is empty.
9. Install the fuel line onto the fuel filter.
10. Slide the hose clamp close to the fuel filter to secure
both the fuel line and the fuel filter (Figure 28).

Replacing the Fuel Filter
